Description
Technical field
The utility model relates to power transmission and distribution switch cubicle field, is specifically related to breaker open operation spring.
Background technology
In the breaker operator module of solid insulation cabinet, combined floodgate axle is after combined floodgate, tripping spring meeting automatic energy storage, tripping spring in existing breaker operator module can not carry out the load of regulating spring according to moment of torsion required during separating brake, therefore, be unfavorable for the debugging of circuit breaker, the elastic force of tripping spring may be caused not enough or too large, separating brake or combined floodgate cannot be realized smoothly.
Summary of the invention
The purpose of this utility model is for existing breaker open operation spring Problems existing pointed in background technology, provide a kind of can the breaker open operation spring of regulating spring elastic force.
The technical scheme realizing goal of the invention of the present utility model is as follows:
A kind of breaker open operation spring, it comprises spiral helicine spring, be connected to the adjusting part of the regulating spring length of spring one end and be connected to the connector of the spring other end, adjusting part comprises holder, spring thread joint pin and adjusting bolt, the outer wall of spring thread joint pin is provided with the helicla flute matched with spring, spring is fixedly connected with spring thread joint pin by this helicla flute, the center of spring thread joint pin is provided with axial internal thread hole, adjusting bolt and spring thread joint pin are threaded connection, locking nut is had between adjusting bolt and holder, to adjust after length adjusting bolt and holder and tight, prevent from rotating, the connecting lever that described connector comprises spring hanging plate and is connected with breaker main shaft, spring hanging plate and connecting lever pass through pinned connection.
In such scheme, the spring on described spring hanging plate comprises several left hole and right ports through hole, and left hole is corresponding with the track of spring spiral process with the distribution of right ports.
In such scheme, described holder comprises integrated base plate, left side plate and rear fixed plate, the body of rod of adjusting screw(rod) passes from the through hole base plate, interior hexagonal (hexagon)nut is at the uppermost limit of base plate, the diameter of interior hexagonal (hexagon)nut is greater than the diameter of through hole, and rear fixed plate is provided with several pilot holes.
The advantage of breaker open operation spring of the present utility model is: breaker open operation spring of the present utility model is assemblied in the breaker module of solid insulation cabinet, can by rotating adjusting screw(rod), adjusting screw(rod) is stretched relative to spring thread joint pin, the length of adjustment sluice separating spring, required separating brake force value is regulated according to the needs of breaker mechanic property, and then the elastic force of regulating spring, the elastic force of tripping spring is enable to meet load needed for separating brake, meanwhile, can ensure that again elastic force can not be excessive.
